Personality wise Lola is more Bianca/Kat/Stacey type then Michelle imo.
Michelle was sort of dowdy compared to the likes of Sharon at the time, she didn't have much but she was more strewed and level headed despite sleeping with Den and Grant, she always want to better herself and the situation she lived in.
bare in mind that's back in the 80s EE was more kitchen sink drama and much more gritty realism then now, I think unfortunately for Lola there is so many similar females that she sort of gets lost in the hustle.
